Initially I thought it was crap. I mean I saw the "what a twist" coming from the first few minutes of the game and felt it was "confirmed" about 1/3 of the way through. Then everyone started raving about how awesome the "twist' was and how "no one saw it coming" etc...
A few months ago Shamus Young basically laid the entire plot out in a critique/review and it reminded of how much I thought the writting was actually good (if not great). Game play was weak sure, and being as "genre savy" as I am on "Asian Marital Arts" stories I saw the twist coming... and yet his write up reminded of all things I liked when I played it through... and Jade Empire was good enough for me play it all the way through to the end first go, despite what I saw as it's flaws. Which is pretty rare.*
So yeah... I'd like see another Martial Arts RPG set in the Jade Empire.
* For instance it took two tries to get through Fallout 1 (F2 was finished in 1 go), I've never actually finished any Elder Scrolls game even though I love a few of them to pieces, it took 6 goes to get through Fallout 3 and I've never finished F:NV (even though NV is far superior to 3), it took 3 tried to finish Fallout Tactics... the only Warcraft game I finished in the first playthrough was 1, the others both took several tries before I had the stamina to go all the way. I did finish Starcraft and Broodwar in the first (and every subsequent) playthrough so, that's something different. I also managed to finish every Deus Ex and System Shock game in the first playthrough (and in subsequent playthroughs where applicable). I finish Diablo 1 and 2 in on every character (and the expansion for about half the characters).
I do though finish almost every non-rpg turn-based strategic or tactical game I've ever played, but's a whole different kettle of fish.
Oh, I finished every Thief game on the first go and failed to finish any S.T.A.L.K.E.R. games (they're too scary ) even though I do love S.T.A.L.K.E.R.
